Incubator PMC report for November 2015
The Apache Incubator is the entry path into the ASF for projects and
codebases wishing to become part of the Foundation's efforts.
There are 47 podlings currently undergoing incubation.
With 702 messages to general@incubator, October was one of the heaviest
months for email traffic in a long time.
Podlings nearing graduation received extra scrutiny this month, presumably
as an indirect result of various recent proposals to rework graduation to
include more structured review. Such evaluations of podling readiness,
while illuminating, put stress on the Mentors and contributors to the
podling under the microscope and raise the overall tension in the
Incubator.
Another topic of discussion was disengaged Mentors. An initiative to engage
Mentors privately when podlings do not report for two months or more yielded
positive results, with some Mentors reaffirming their commitment and others
officially moving on.
* Community
New IPMC members:
- Tom Barber (magicaltrout)
- Patrick Wendell (pwendell)
- Reynold Xin (rxin)
- Phil Sorber (sorber)
- Julien Le Dem (julien)
- Jacques Nadeau (jacques)
No one left the IPMC this month, but a handful of Mentors have stepped
down from their posts with various podlings. Most of the resignations
were from Mentors who had become inactive, so the Incubator's rolls have
become a bit more accurate.
* New Podlings
- Eagle
- Mynewt
- Concerted
- SystemML
* Graduations
The board has motions for the following:
- Brooklyn
- Groovy
- Kylin
- REEF
* Releases
The following releases were made since the last Incubator report:
- 2015-10-05 Apache Johnzon 0.9.2-incubating
- 2015-10-07 Apache Singa 0.1.0
- 2015-10-14 Apache AsterixDB 0.8.7-incubating

- 2015-10-31 Apache Slider 0.81.1-incubating
* IP Clearance
- Taobao (China) Software Co., Ltd and several individuals donated Alibaba
JStorm, "A fork of Apache Storm with Clojure code replaced with Java,
and several other improvements".
A discussion calling into question what responsibilities -- if any -- the
Incubator should have with regards to IP Clearance eventually went quiet,
leaving the status quo intact.
* Miscellaneous
- Droids has retired.
- Kalumet has retired.
- The Corinthia community is voting on retirement.

Apex
Apex is an enterprise grade native YARN big data-in-motion platform that
unifies stream processing as well as batch processing.
Apex has been incubating since 2015-08-17.
Three most important issues to address in the move towards graduation:
1. Release Apex-Core, and Apex-Malhar on ongoing basis.
2. Grow contributors beyond the initial set.
3. Move to using Apache JIRA
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
The project is still using the original Atlassian instance of JIRA.
INFRA-10144 has tracked the Apache JIRA migration request since August.
How has the community developed since the last report?
The community is very engaged with the development of the project. There
have been 788 messages on dev@ for October.
The community has been active building meetup groups in various locations:
http://s.apache.org/jKT
- Number of meetups: 6 in total so far: 4 in USA cities and 2 in Indian
cities
- Total members in worldwide Apache Apex meetups: 495
- Events: 1 in Oct; 4 scheduled in Nov: CapitalOne presentation in
Chicago; DataTorrent presentation in Pune; GE presentation in San Ramon;
PubMatic presentation in San Jose;
Future: Planning to start meetups in more cities, and be able to organize
2-3 events a month.
How has the project developed since the last report?
The first release under incubation passed voting. Apex (Core)
3.2.0-incubating was released 2015-10-30. The community is currently
discussing roadmap for upcoming releases.
Various metrics are as follows:
+---------------------------------------------------+
| Metric | Core | Malhar |
+---------------------------------------------------+
| Non Merge Commits | 159 | 39 |
| Contributors | 15 | 9 |
| Jira New Issues | 58 | 19 |
| Resolved Issues | 34 | 30 |
+---------------------------------------------------+
The next release target is Apex Malhar with release candidate expected
fist week of November.
Date of last release:
2015-10-30 Apex (Core) 3.2.0-incubating

Shepherd/Mentor notes:
Chris Nauroth (cnauroth):
The community continues to show great, open development activity on the
mailing list. The first release was handled well with careful attention
to detail when IPMC members requested a second RC with some changes. I
would like to request that the infra team prioritize completion of the
JIRA migration tracked in INFRA-10144.
Alan Gates (gates):
There have been some questions regarding which committers in the project
are also on the PPMC. Originally only 6 developers were proposed for
initial committers, but as part of the entry to incubation this was
expanded to the current 30+. The understanding of some in the project
was that the PPMC still only consisted of those original 6, while the
other ~24 devs were just committers. The mentors have explained that it
does not work this way. The community is talking through how to
approach this disconnect. The mail thread is at
<http://s.apache.org/qsV>.
--------------------
AsterixDB
Apache AsterixDB is a scalable big data management system (BDMS) that
provides storage, management, and query capabilities for large
collections of semi-structured data.
AsterixDB has been incubating since 2015-02-28.
Three most important issues to address in the move towards graduation:
1. Do an Apache release that can also provide binary artifacts with
correct LICENSEs and NOTICEs.
2.
3.
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
The discussion on the use of an external Gerrit instance for code
reviews is considered to be resolved.
The current workflow ensures that
a) The ASF git repository is the canonical repository for the project.
b) Only committers can manually commit changes to the ASF git
repository.
c) All discussions on the Gerrit instance are sent to
notifications@asterixdb.incubator.apache.org.
While it would be good to also have the Gerrit instance run on ASF
hardware, this is neither necessary to document the provenance of the
code nor to enable list members to follow and participate in the
activities of the project. Also, there seems to be no infra capacity
to provide a Gerrit service.
How has the community developed since the last report?
- A paper on AsterixDB was presented at VLDB'15.
- A deep-dive introduction to AsterixDB was given at the first
workshop on Big Data Open Source Systems (BOSS'15).
- Chris Hillery was added as a committer on Oct 20.
- Increased traffic on the users list.
How has the project developed since the last report?
- All Google Code issues were migrated to the ASF JIRA and triaged.
- The discussion on the use of an external Gerrit instance for code
reviews is considered to be resolved.
- AsterixDB 0.8.7 and the associated Hyracks 0.2.16 were released.
Date of last release:
2015-10-22 AsterixDB 0.8.7
2015-09-22 Hyracks 0.2.16

oriented climate model performance evaluation and diagnosis through the
comprehensive and synergistic use of multiple observational data, reanalysis
data, and model outputs.
Climate Model Diagnostic Analyzer has been incubating since 2015-05-08.
Three most important issues to address in the move towards graduation:
1. Increase email and communication traffic
2. Build a CMDA website at Apache
3. Learn more about Apache way
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
The project is still in its nascence and the PPMC is still learning the
Apache way and moving out of JPL/CMU centric development. The project team
wants to do a good job they are just moving along slowly.
How has the community developed since the last report?
More commits and code are being done on the Apache Git repo, almost
exclusively. They still come in bulk rather than incrementally. Also
notes from meetings held between JPL and CMU project members are being
flushed to the list to increase awareness and participation.
How has the project developed since the last report?
1. Deployed to the Amazon Cloud (AWS);
2. Students from the 2015 JPL center for climate sciences summer school
used the Amazon Cloud deployment for class projects;
3. New design and implementation of front end web interface for
flexibility and to facilitate provenance;
4. Acquired new ECMWF data;
5. Created a knowledge graph based on provenance accumulated from the 2015
Summer School usages;
6. New services to come soon: Random Forests and Empirical Orthogonal
Function Analysis (EOF).
More code is coming. Need to do a website, and start to use
issue tracking, etc.

Shepherd/Mentor notes:
Ted Dunning (tdunning):
There was a bit of confusion about the graduation vote (which passed,
but not unanimously). IPMC and Kylin project members are working to fix
the issues to the satisfaction of the IPMC member who voted -1.
Marvin Humphrey (marvin):
The issue that was raised by the IPMC Member voting -1 was acknowledged
as legitimate by multiple IPMC members, and a plan of action was
proposed which was endorsed by one of the Kylin Mentors. So while there
may have been differences of opinion about urgency, the matter has been
guided steadily towards a constructive resolution.
(update) The -1 has been changed over to a +1 and the issue resolved.
--------------------

previous tool. 18 JIRAs created and 2 resolved in last 30 days.
3. All commits and code are now being done on the Apache Git repo.
4. Three new quick start guides have been written: i) install, ii) user,
and iii) developer. The goal is to make it easier to onboard new
community members.
5. A new Greenplum DB sandbox VM with MADlib pre-installed has been
created and made available publicly at
https://github.com/greenplum-db/gpdb-sandbox-tutorials. The goal is to
make it easier to onboard new community members - they can download and
start trying MADlib right away with no install/setup.
6. A "catchup JIRA" was filed
https://issues.apache.org/jira/browse/MADLIB-912 in order to catch up
between the time of the code grand to Apache and bringing in dev work
that was already in flight at the time. We apologize for any
inconvenience in clubbing together these multiple items; it was a
one-time operation.

REEF voting on graduation.
--------------------
Rya
Rya (pronounced "ree-uh" /rēə/) is a cloud-based RDF triple store that
supports SPARQL queries. Rya is a scalable RDF data management system built
on top of Accumulo. Rya uses novel storage methods, indexing schemes, and
query processing techniques that scale to billions of triples across
multiple nodes. Rya provides fast and easy access to the data through
SPARQL, a conventional query mechanism for RDF data.
Rya has been incubating since 2015-09-18.
Three most important issues to address in the move towards graduation:
1. Populate the website for the project
2. Become familiar with the release process and have a first release as
part of the Apache
3. Create a "how to" document to explain the ways new contributors can
become involved in the project, so we increase the size of the
community.
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
No
How has the community developed since the last report?
All initial committers submitted their ICLAs and are subscribed to the dev
and private mailing lists. There are 32 subscribers to the dev list. The
initial committers are learning to use the Apache infrastructure and
processes. We gave a presentation on Rya at Duke University, trying to
increase awareness about the project.
How has the project developed since the last report?
Infrastructure is now set up (mailing lists, repositories, JIRA, etc)
Getting the code reviewed for final publication took about 3 weeks, which
was longer than we expected, but the code is now imported into the Apache
git repository. We are working on creating a website for the project.
Date of last release:
Not applicable - the code was just imported into Apache repository
When were the last committers or PMC members elected?

Shepherd/Mentor notes:
Sean Busbey (busbey):
Getting things started took a bit, presumably due to the review needed
to get the code out, but the fledging community has been responsive to
feedback. The next month should give a better idea of how strong a hand
the mentors will need to use.
--------------------
Slider
Slider is a collection of tools and technologies to package, deploy, and
manage long running applications on Apache Hadoop YARN clusters.
Slider has been incubating since 2014-04-29.
Three most important issues to address in the move towards graduation:
1. Getting more external users
2. Getting more diverse set of developers
3. Getting more diverse set of committers/PMC
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
No
How has the community developed since the last report?
We are seeing traction in the community with a number of new users
requesting improvements in deployment and management of applications
using Slider. Patches were submitted by a couple of new contributors.
We still have to get those people into long term coding, and then bring
them in to the committer group.
How has the project developed since the last report?
We released a slider-0.81.1-incubating bug fix release with 30 JIRAs
resolved and have begun discussing the 0.90.0 release.
Date of last release:
2015-10-29 slider-0.81.1-incubating

Tamaya
Tamaya is a highly flexible configuration solution based on an modular,
extensible and injectable key/value based design, which should provide a
minimal but extendible modern and functional API leveraging SE, ME and EE
environments.
Tamaya has been incubating since 2014-11-14.
Three most important issues to address in the move towards graduation:
1. Make the project known in projects world-wide.
2. Release more often.
3.
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
No.
How has the community developed since the last report?
We have new people joining the mailinglist and also starting
discussions for possible future involvement. We had quite broad
feedback in the Java EE space, since we added full blown CDI
support to Tamaya. We are looking forward to gain new committers
within next reporting period hopefully.
During ApacheCon Europe different projects found our approach
very interesting. We also have a request from a JUG in Switzerland
going to present the project as well several conferences that accept
the topic as well.
How has the project developed since the last report?
The project's API has proven to work very well. Many, also complex
extensions were written and we started to add support for very
important eco-systems (JavaEE, Spring, OSGI).
I think we can release the next release before X-Mas the latest.
Date of last release:
2015-08-22
When were the last committers or PMC members elected?
See last report (no new committers or PMC members).

TinkerPop
TinkerPop is a graph computing framework written in Java
TinkerPop has been incubating since 2015-01-16.
Three most important issues to address in the move towards graduation:
1. Add more members to the PMC.
2. Add more members to the committer list.
3. N/A (unless the mentors have ideas?)
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
No. Recently, we have really appreciated Daniel Gruno's (mentor) efforts
to get our development community more connected by setting up an Apache
HipChat account for us and interacting with us in a more real-time fashion
on various procedures/policies of Apache in a proactive manner. This has
helped to explain to us (through doing) what is required of Apache.
How has the community developed since the last report?
We have 2 new committers: Jason Plurad and Matthew Frantz. We are in the
process of [DISCUSS] about two other potential committers.
How has the project developed since the last report?
We have since instantiated a 'review-then-commit' model. Daniel Gruno
(mentor) worked with us to set the appropriate policy documentation and
thus far, it has been going very well.
In terms of the adoption of TinkerPop, note that Amazon recently announced
that they use Apache TinkerPop for their order fulfillment network (1
trillion edges). This is very public discussion of our technology (videos
+ blog posts) should help to attract development talent.
We have compiled a list of the other Apache technologies that TinkerPop
works with: Apache Cassandra, Apache HBase, Apache Hadoop, Apache Spark,
Apache Giraph, Apache Atlas, and Apache Falcon. We bring this up to
identify the integration of Apache TinkerPop into the greater Apache
ecosystem.
The following articles/presentations/blogposts were provided about
TinkerPop from TinkerPop members since the last report:

Shepherd/Mentor notes:
Daniel Gruno (humbedooh):
I will note that despite HipChat and other direct message platforms
involved, the async messages, especially revolving around larger
community/project issues have been on the rise over the past 3 months,
up 71% compared with the 3 months before that, as evident from
<http://s.apache.org/Atz> (this is discounting git and jira messages). I
see this as a positive signal that the podling is working towards a more
open and inclusive discussion pattern. New committers are being
on-boarded, and I hope to see more PPMC members join the ranks soon.
